Good news about the nf7

[Hognert]

Ive had a nf7-s v2 now for a week or so and until just now its been a real disappointment . It could do decent FSB at a low multi but as soon as I increased the multi the max FSB dropped down... a whole lot.
However, today I decided to add some capacitators to the board and see if that might help. The results is nothin but amazing.

This board can now do 250MHz DC with the standard nb cooler and _1,8_V Vdd at just about any multi and with any Vcore I can possibly throw at it . Totally wicked if you ask me .

My memory however (1 stick bh-6 and one bh-5) can only do light benches at 250MHz DC so ill have to stay at 245MHz for now. The board will do that solid at 1,7V Vdd .

So around the socket theres five 6,3V 3300uF rubicon caps. I had a couple of spare 2200uF lying around so I simply added one to each cap on the mobo. Thats the whole trick . I suppose if you got some bigger quality caps you can just replace the original ones. I just might do that myself. I doubt this is somethin that only works good on my specific board and Im sure that you will see some great results if you try it out.

And finally I did a sandra run just to show off .

got pics of the mod?

[Hognert]

Nope, I do got a crappy webcam here though... can take a pic if you really want one. Anyway its just 5 caps soldered to the backside of the mobo . Cant be mounted on a ordinary mobo tray like this, thats why it might be better to replace the original caps with bigger ones.

Now, that's what I call some serious FSB overclocking.

Absolutely fantastic work, Hognert. Good job. Your score is sick high.

The max I've gotten so far is almost 3700 mark on a rev1.2.

[TheDude]

Great Mod! Where and which caps should I get to replace original ones? I have often wondered what replacing some components with really high quality ones would do. Thanks

[Ewok]

and what kinda soldering iron do people use on mb to remove and add these things?

i got one but its kinda old and likes to burn things.

now if thats gonna get me 250fsb ill go buy a soldering iron and some caps and do it.

Great results there!!!
So what uF and voltage caps would i need to buy to totally replace the originals to see ant benefits.....also, i wonder if its worth changing the caps near the mosfets???

[Hognert]

If you are going to replace the original caps with new ones I suggest you scout for caps rated 6,3V and nothing more. The higher voltage rating the bigger the cap will get, and if its to big it simply wont fit on the front of the mobo. Even if they are rated for higher voltage they will of course work just as well.. but size mathers . Capacitivity should be as high as you can find as long as the cap got the same diameter as the original ones.

i have to see this.. post some pics if you could.

[Hognert]

Ill snap some pics tomorrow with a real camera, no point trying with this worthless webcam. Got the beast to pass superpi and pifast at 250 btw... 3dmark is a no go at this speed for now :/.

[Ewok]

hognert any chance you could look on this site

http://www1.rswww.com

and point me at some capacitors that would do the job nicely?

[PCGenious]

Damn dude that is definitely sweet.

[youthemandan]

Can u post a radi shack line or part number?

Will this work??? I don't see the two pins on the bottom?
All i can find is 35v ones.
Edit:
Sratch that. i found these

Can i get them at radio shack?? Cause i really hate to wate for shipping.

Hognert, if this works for everyone, we'll have to nominate this for mod of the year!

Hurry up and get some pics! Also, what could you do FSBwise before and after the mod. We need to have some idea of how much improvement we might expect.

[CodeRed]

Mod of the year for sure.

If it works for me I'll name my next child after you ....



well maybe not

Hognert,

I was thinking of using the Rubycon ZL series Ultra Low Impedance caps. The diameter is nice and small so they may fit on the underside of the mobo, they also have a very high max ripple current ... dont want exploding caps.

specs
2200uF, 6.3V DC, 2150 mA max ripple, 0.022ohms, -50 to 105 deg C, length 23 mm, diameter 10 mm

Farnell part no 768-005

Do they sound alright to you?

[Ragnarok]

Cant wait for the pics, definately a mod to try on my NF7-S 1.2

[deathstar13]

dang i can stop blaming my cpu for being a wuss!
well im not gonna do the mod as im a wuss also.but ive had this issue and talked about it many times at least now i know the true answer.

[WildKard]

That is quite interesting indeed! I am wondering now if possibly people with boards that clock low, have lower quality caps, and people with extreme clocking boards have great caps...it sounds very possible!

[LORD]

LOL, last time I added caps on a board was on an KT7A v1.0. I ended up taking them off all the same cause the cpu didn't really increase in speed which is what I was after at the time.

Just didn't think of trying far higher fsb speeds back then.

[Hognert]

Good morning everyone . Will get you some pics later today.. need to rip the board out and bring it over to some friend with a camera...

Last thing I did last night were to replace the 2200uF caps with some 10V 4700uF. These suckers are pretty big and the board is actually a little more stable now. Not much at all though so adding some 2200uF ones should do the trick quite well.

Edit: This board could at a very low multi do about 240 before. That with water cooled nb and 2,3V vdd. Actually posted at 250 with a pelt on the nb but could not boot. At a multi like 11 (the one I use now) I guess it could do just over 230 ... and that with a very high Vdd. With only 1,8V (no need to go any higher now) I doubt it could do more then 220MHz.

[Hallowed]

Thats very trick.

I will definately do this, and a photo shot would be excellent confirmation.

Thnx for the heads up Hognert, and one excellent mod.

[Ewok]

i cant seem to find any 4700uF ones that are at least the same size as the ones already on there. it looks like the ones already there are 8mm diamater. all the 4700uF ones i can find are at least 12.5mm and most are 16mm so they not going to fit because 4 of them are right next to each other on the board.
